Title: The Innovative Contributions of Ann M R Larson

Introduction

Ann M R Larson is a notable inventor based in Appleton, WI (US). She has made significant contributions to the field of electrical steels, particularly through her innovative patent. Her work has implications for various industries that rely on high-performance motor lamination steels.

Latest Patents

Ann holds a patent for a process of making electrical steels. This process involves batch annealed, semi-processed, and fully processed motor lamination steels. The method subjects a slab with an ultra-low carbon composition of less than 0.01% to several steps, including hot rolling the slab into a strip and coiling the strip. The sequential steps include annealing the strip in coil form, cold rolling the strip, and batch annealing the strip in coil form. The strip is then flattened through a temper rolling or leveling process, which reduces its thickness by an amount ranging from greater than 0% to not greater than 1.0%. This flattening step provides the strip with a permeability of at least 2500 Gauss/Oersted when stress relief annealed.
